"This is not the outcome anyone wanted, but ... we have some closure for the family," Port Clinton Police Chief Robert Hickman said Tuesday.

The cause of death was determined to be compressive asphyxia, Ottawa County Coroner Dr. Dan Cadigan said in a news release. The manner of death has been deemed accidental by the coroner's office.

Harley, 14, was last seen December 20 in Port Clinton as he left for school between 6 and 7 a.m., police said.

At least 75 law enforcement agencies have scoured more than 150 acres with helicopters, trained dogs and search-and-rescue teams, Port Clinton police said.

During another sweep of the area Monday, authorities zeroed in on a vacant summer home that was undergoing renovation.

There were no signs of forced entry to the house, and there was a lockbox for keys, Hickman said.

Police went in and discovered a tragic scene.

"Harley's coat, glasses were discovered on the second floor of the house next to a brick chimney," Hickman said.

"We were then able to discover what we believe to be Harley, who was caught in the chimney."

Final identification of the body is still pending and final autopsy findings are awaiting toxicology results, the release says.

"This appears to be an accident," the police chief said.

"It appears Harley climbed an antenna tower to the roof and entered a chimney. Once in the chimney, Harley's jacket and glasses were pushed from the chimney, through a flue, and into the second floor of the house. The chimney was blocked between the second and first floor, which trapped Harley."
